Myth 2: This is the BIG one: those 'professionally' diagnosed with dyslexia have inherited a brain defect. As a result of this 'neurodevelopmental flaw' they lack phonemic awareness and manipulation ability (PA), having failed to progress through what is deemed to be the biologically-dictated development of speech sound awareness: beginning with whole spoken words, progressing down in size through syllables, then rhymes to the smallest units of sound: the phonemes. This final stage is supposed to occur naturally in children without the brain glitch by the age of 6-7. See http://www.dyslexics.org.uk/main_method_2.htm
Skipping over the earlier 'developmental' stages by explicitly teaching phoneme-grapheme correspondences from the very beginning of instruction, as happens in high quality phonics programmes, especially if children are younger than 6-7, is believed to be potentially damaging to children's 'natural' development of PA, likely to exacerbate the difficulties of those who harbour the faulty brain wiring and could harm children's love of reading.
Facts:
The ability to identify and process the individual phonemes in the speech stream of the people talking to and around them is innate and universal in young babies, but they are not consciously aware of this ability. Babies use this 'wired-in' phonemic ability to identify and manipulate the individual phonemes in their native language/s on their journey to develop speech. By the time they are a year old, their phonemic ability has faded into the background of the brain, accessible (though not always easily-see below), but never needed consciously unless, some years later, they have to learn to decode and spell using an alphabetic writing system. (D.McGuinness. GRB p33-35)
PA is essential (but not sufficient) for learning to decode and spell when a writing system uses an alphabetic code, but not if a different writing system (syllabic or diphonic) is used. Studies ''show the strong impact of the type of writing system and type of instruction on the development of phonemic awareness - an environmental effect, and restates the point that you do not acquire this aptitude unless you need it'' (D.McGuinness WCCR p135). ''(T)he ability to manipulate speech sounds is a taught skill, not an outcome of cognitive maturation or exposure to language'' (Rice/Brooks p54)
Whilst a tiny percentage of children become aware (conscious) of the phonemes and graphemes in their environment early on and seemingly effortlessly, and put the two together (''the rapid graspers'' DfE) through a lucky combination of nature and nurture, because of the complexity of the English alphabetic code, most pupils need an extensive period of high quality phonics instruction in order to become fluent and accurate decoders and spellers.
Even when taught by expertly trained teachers using high quality phonics, children will not acquire PA at the same rate*. ''(T)he ability to access the phoneme level of speech is heritable...on a continuum of innate ability'' (D.McGuinness WCCR p151)  Hearing difficulties in the early primary years can also, unsurprisingly, slow down PA acquisition but often goes undiagnosed-see http://www.dyslexics.org.uk/is_my_child.htm
A child's position low on the PA acquisition curve is unlikely to be apparent (level of intellect, vocabulary size and rhyming ability are poor indicators)when they begin school, so providing high quality phonics instruction to all children from the start is essential to prevent word decoding difficulties appearing. Those low on the PA curve and those with hearing difficulties will fall into that small group of pupils who are highly likely to need regular 'keep-up' phonics tutoring in addition to whole-class phonics teaching.
* Falling on the lower end of the PA acquisition curve is not the same as having a brain defect. Any child, apart from those with severe cognitive and perceptual impairments (less than 5% of the population), can be taught to recognise and manipulate the individual phonemes of the English language using high quality phonics instruction **which includes the graphemes.
** ''Phoneme analysis sufficient to be able to decode is acquired much more rapidly in the context of print than in isolation'' (D.McGuinness. Response to Hulme) ''Lots of studies showing kids do better when phonemic awareness tasks are tied to print. Phonemes emerge in part from exposure to print'' (Prof. Mark Seidenberg) ''Teaching children to manipulate phonemes using letters produced greater effects than teaching without letters'' (USA.National Reading Panel) Further reading: D.McGuinness's book: Language Development & Learning to Read p37-> 'A Theory Becomes Dogma'

Myth 3: Children who fail to learn how to decode and spell single words fluently and accurately from a school's whole-class (wave/tier 1) reading instruction using the 'balanced approach' and continue to fail, despite being subjected to one or more (RTI. wave/tier 2 and 3) interventions (see http://www.dyslexics.org.uk/room_101.htm), are ''phonetically deaf'' and ''treatment resisters''. They can, at last, be legitimately labelled as dyslexic.
Facts:
Unless the student falls into the tiny percentage of the population who ''have severe cognitive impairments that would make acquiring reading skills extremely difficult'' (Eab.com. Narrowing the Third-Grade Reading Gap), the most likely reason why they continue to struggle to decode single words accurately is dysdidaxia (a problem with the teaching) (Macmillan p134). ''We know that the intellectual crippling of children is caused overwhelmingly by faulty instruction -not by faulty children'' (Engelmann&Carnine 1982.Theory of instruction). ''(F)ailure to read is often to do with the nature of the teaching rather than the nature of the child'' (Rose 2009 p60)
''The Response to Intervention [RTI] framework was devised as an alternative to the discredited IQ /Achievement Discrepancy “Model” for the designation of “Learning Disability.” Schools and teachers find the newer “Model” attractive because it takes the “problem kids” out of mainstream instruction while sustaining present instructional practices and maintaining the turf of psychologists and “Special Education” specialists. Parents find it attractive because the children involved are receiving increased personal and specialized instructional attention. By the time a child has gone through Tier 3 [England.Wave 3], the child, parents, and school personnel are thoroughly convinced that the child has a “disability.” The tragedy/travesty is that the “problem” the child had when first identified as “at risk” has morphed into a “really big problem” for which the child bears the full responsibility'' (Prof.Schutz)
''I think many do not understand RTI, specifically the need for Tier 2 to intensify good practice from Tier 1. Even a sound Tier 2 program won't help if Tier 1 is based on ineffective practices such as balanced literacy'' (Dr. Kate de Bruin.Twitter)
''Phonetically deaf'' children are rare in mainstream schools that teach high quality synthetic phonics from day one: at St George's primary school in Wandsworth, London, an area of high deprivation, all the children (boys and girls, summer-born, in receipt of free school meals...) reached the expected standard in the phonics decoding check 6 years in a row, and all the children in Y1 and Y2 (2018) spell at CA or better.

Myth 4: The prevalence of dyslexia is estimated to be somewhere between 4%- 8% of the UK population (Rose 2009 p11) and up to 20% in the USA.
Facts:
''Any attempt to determine the prevalence of dyslexia should be treated with caution'' (Miles p27).''In the absence of a definition that provides unequivocal identification criteria, all statements about prevalence are guesses; they are value judgements, not scientific facts...The British Dyslexia Association's prevalence estimates of either 4 per cent for severe dyslexia or 10 per cent to include mild dyslexia have been described as both theoretically and technically contentious'' (Rice/Brooks p19-20)
All that can be said with any certainty is that in every English-speaking country a significant percentage of the population have single word decoding and spelling difficulties varying from mild through to severe.

Myth 5: Those who have been professionally diagnosed as having ''specific learning difficulties consistent with dyslexia'' need a special sort of intervention which is different from that deemed suitable for 'common-or-garden' struggling decoders and spellers. Furthermore, this special instruction should only be delivered by qualified teachers who have undertaken a long and expensive training course which has been approved and accredited (and often provided) by one of the powerful dyslexia lobby groups***
Facts:
Having thoroughly checked the government's use of evidence in policy-making on dyslexia, the UK Parliament's Science and Technology committee concluded that, ''The government should stop talking about specialist dyslexia teaching. Children diagnosed with dyslexia and children who struggle with reading for other reasons, are taught how to read in exactly the same way''. The committee also said that, ''(T)he Government should be more independently minded in the formulation of dyslexia policy: priorities appear to be based on pressures from lobby groups rather than on research'' (S&T committee pressnotice 18/12/09)
Whatever their age or IQ, students who have serious difficulties with single word decoding and spelling need intensive, one-to-one, high quality phonics instruction, not ''something different (from phonics)'' see- What NOT to teach.

Myth 6: Those professionally diagnosed with dyslexia have other difficulties such as poor short-term memory, sequencing problems and rapid naming deficits (RAN) in addition to their very slow and inaccurate single word decoding and spelling. These other difficulties can be used to confirm the diagnosis of dyslexia  The number and type of co-occurring difficulties vary from one dyslexic person to another, as does the severity.
Facts:
These are 'soft' signs - not based on data that is readily quantifiable or amenable to experimental verification. ''Forget about letter reversals, clumsiness, inconsistent hand preference and poor memory - these are commonly found in people without reading difficulties, and in poor readers not considered to be dyslexic'' (Prof.Elliott .TES) ''(D)yslexia has been linked erroneously to left-handedness, balance deficits, persistence of infant reflexes, visual perceptual abnormalities and nutritional deficiencies'' (Snowling. BDA website news17)
''The fact that RAN (rapid automatic naming tasks) using digits and letters predict reading so much better than RAN colours and objects do, means that naming speed per se is not a factor in learning to read.'' (D.McGuinness LDLR p388) ''Naming objects and colours is a truer reflection of natural or biological based ability'' (D.McGuinness WCCR p131)
Many so-called dyslexia symptoms such as b/d confusion and word reversal are simply the consequence of poor teaching and lack of practice.

Myth 7: Dyslexia is caused by inherited, faulty genes with evidence coming from studies of twins.
Facts:
As there is no operational definition of dyslexia, it is not possible to find true dyslexic individuals as subjects for a scientifically valid study. This means that the results of all the heritability studies and genetic models of dyslexia are invalid: ‘'The twin studies leave a lot to be desired, starting with the identification of their subject 'dyslexics'. Most such work is done with the University of Colorado and their Prof. Olsen has recently (after the IQ-achievement criterion died) stated that the bottom x% of the bell curve of reading ability can be considered 'dyslexic’ and this is great because ''if we deploy the bell curve of normal distribution we can bring the big guns of statistics to bear''. This is outrageous, of course. The bottom x% are not to be presumed all to have the same neurological deficit (or any at all) with no demonstration of same'' (Kerr. RRF message board 29/09/09).
Claims to link a complex, learned behaviour that has to be taught (not part of species specific trait) to a gene complex, can only be bogus. ''Thus, contrary to what practitioners may sometimes suppose, family relationship (familiarity) alone is not a reliable indicator of genetic heritability'' (Rice/Brooks p32)
In English-speaking countries where, every year, at least 20% of children leave school functionally illiterate, nearly everyone has a relative (or several) who failed to learn to read.

Myth 8: Dyslexia is a visual problem - dyslexics sometimes see letters reversed, words transposed or moving around.
Facts:
Prof. Vellutino showed this was incorrect when he ''asked dyslexic and non dyslexic American children to re-produce Hebrew letters none of them had seen before... the poor readers performed as well as the normal readers in reproducing Hebrew letters from memory...Absolutely no differences between the two groups. If anything the normal readers made more errors than the poor readers, so the poor readers could see the materials as well as the normal readers'' (Mills. The Dyslexia Myth)
''Teams from Bristol and Newcastle universities carried out eye tests on more than 5,800 children and did not find any differences in the vision of those with dyslexia...Where there were dyslexic children with eye problems, the occurrence was no more likely than for non-dyslexics, the study found. And a large majority of dyslexic children were defined as having "perfect vision" http://www.bbc.co.uk/news/education-32836733
A subset of this myth is that 'dyslexics' can be helped by providing them with reading materials printed using a special 'Dyslexie' font on tinted paper. https://onlinelibrary.wiley.com/doi/abs/10.1002/dys.1527
See http://www.dyslexics.org.uk/room_101.htm for full information on 'Visual Therapies' especially the use of coloured lenses and overlays.

Myth 9: fMRI brain scan studies show that dyslexics' brains work differently from non-dyslexics' brains.
Facts:
In addition to the impossibility of finding true dyslexics as subjects for a scientifically valid study, ''The recent studies using fMRI, convincingly show what everybody who knows anything about the brain can tell you, that when someone can't read, images of his brain taken while he is trying to read will look different to someone who can read. Furthermore, when the poor reader is taught to read, the patterns of his brain metabolism will look identical to someone who can!'' (D.McGuinness. Response to Hulme)
''(T)here is a mistaken belief that current knowledge in [genetics and neuroscience] is sufficient to justify a category of dyslexia as a subset of those who encounter reading difficulties'' (Elliott/Gibbs p475)
Dyslexia: Still Not a Neurodevelopmental Disorder.
https://www.mdpi.com/2076-3425/9/1/9
"We recently pointed out that there is no evidence to support the commonly held view that there is something wrong with the brains of children who have great difficulty learning to read ..."

Myth 10: The planum temporale area of the brain is 'abnormally symmetrical' in dyslexics.
Facts:
This claim is based on the dissection of just a small number of brains taken from people previously diagnosed as 'dyslexic'. The lack of an infallible definition for dyslexia, along with the tiny number of research subjects, makes this study's conclusions scientifically invalid; ''35 percent of the population have symmetrical brains. Symmetry is not pathology''. (D.McGuinness WCCR p118)

Myth 11: Short-term memory deficit is a hallmark of dyslexia (NTF.p6)
Facts:
Poor short-term memory ''is the symptom most often quoted as distinguishing dyslexics from other poor readers, and those who have difficulty reading are more likely to suffer from it. Yet, however disabling poor short-term memory may be, evidence suggests it neither causes reading difficulties nor predicts the outcome of intervention. In a highly regarded study conducted by Joseph Torgesen, a psychologist at the University of Florida, out of 60 children with severe reading difficulties, only eight had poor short-term memories, while almost as many – seven – had very good short-term memories'' (David Mills.http://www.telegraph.co.uk/health/children_shealth/3347022/Dyslexia-a-big-expensive-myth.html)

Myth 12: Dyslexia is an incurable brain defect. It ''will not go away with tuition, practice, hard work etc'' (Klein quoted in Kerr p113)
Facts:
''Shaywitz and others in the Connecticut Longitudinal Study followed children to see if the discrepancy diagnosis of dyslexia was constant from one grade to another. 25 children were diagnosed dyslexic in first grade and 31 in grade 3, but only 7 were classified as dyslexic in both grades. Of the 24 children classified as dyslexic at fifth grade, only 14 were also dyslexic in third grade'' (D.McGuinness. WCCR p136-7).
If struggling decoders are given expert synthetic / linguistic phonics tuition early enough (large differences in reading practice begin to emerge as early as the middle of the first-grade year (Stanovich p 162)) in their education, their dyslexia will 'go away'. Sadly, unless high quality phonics tutoring is put into place extremely quickly, along with complete cessation of multi-cue word reading, the negative side effects of early mal-instruction such as the 'bad habit' of guessing and a dislike of reading and writing, are likely to persist and fluency is unlikely to ever be achieved. If newly taught code knowledge and skills are not practised extensively they are bound to erode too.

Myth 13: Dyslexics are compensated for their lack of phonemic awareness and weak decoding skills by being naturally gifted in the creative / visual-spatial sphere: Famous dyslexic chef Jamie Oliver thinks that ''children with dyslexia are 'lucky''. In his book, 'David and Goliath', journalist and author Malcolm Gladwell describes dyslexia as ''a desirable difficulty'' (see Prof. Seidenberg's book 'Language at the Speed of Sight' p178-185 for a critique). The 'Made by Dyslexia' charity suggests that ''Dyslexia can be a blessing'' (The Times. Oct 2020)
Facts:
Comforting though this idea may be for some, it is simply ''opinion bolstered by anecdote''.
''Being unable to read is not a gift, not a superpower and sending this message of dyslexics being special is really unhelpful'' 
(Amanda, parent of a 'dyslexic' child. Twitter)
The late Martin Turner, formerly head of psychology at Dyslexia Action, said that it was a 'travesty' to talk about dyslexia as a bonus when it caused such suffering. ''It's a myth that there are compensatory gifts. Dyslexics go into the visual arts like sheep head for a gap in the hedge. They aren't more creative, they are more stressed.'' (Jardine) In a review of the research on dyslexia, Dr. Rice and Professor Brooks came to the same conclusion. ''On anecdotal evidence, the belief that 'difficulty in learning to read is not a wholly tragic life sentence but is often accompanied by great talents' may seem attractive. However, systematic investigation has found little if any support for it.'' (Rice/ Brooks p18)
The late 'dyslexic' journalist AA Gill confirmed this view when he wrote, ''In truth, of course, dyslexics end up in the art room or the music studio or the drama class after school, because it’s the only place they aren’t special-needs remedial. They get good because they can’t do anything else.''
(Times 08/04/07)
When researchers at the University of Edinburgh tested 'the hypotheses that those with reading disability are compensated with enhanced creativity', they found that, ''Stronger reading was in fact linked to higher creativity, controlling for IQ'' http://www.sciencedirect.com/science/article/pii/S104160801300040X
More recently, researchers in Chile explored the links between reading skills and creativity. Their findings did ''not support the hypothesis that specific reading disability is associated with better performance on creative tasks''

Myth 14: Dyslexia can be accurately diagnosed by an educational psychologist or a 'specialist dyslexia teacher' using special tests.
Facts:
No scientifically valid tests are available that can differentiate the dyslexics from other poor decoders: ''After three decades as an educationalist, first as a teacher of children with learning difficulties, then as an educational psychologist and, latterly, as an academic who has reviewed the educational literature, I have little confidence in myself (or others') ability to offer a diagnosis of dyslexia.'' (Prof.Elliott. TES)
Because of their inability to give a legitimate diagnosis (there is no legal definition of dyslexia in England Singleton p16), a specialist dyslexia tutor or educational psychologist's written report is very unlikely to include the concrete label of dyslexia. Instead, it will substitute words such as, ''has a specific weakness in phonological development'' (see Myth 2), or it will be hedged about with words that avoid commitment to a definitive diagnosis: ''exhibited a pattern of difficulties characteristic of dyslexia'' (see Myth 6), ''has a dyslexic profile'' or ''is at risk for Dyslexia-SpLD'', with the discrete 'dyslexia' label only given to parents verbally. See 'Should I have my Child Assessed?'

Myth 15: Dyslexia can be found world-wide.
Facts:
In countries which have a transparent writing code (e.g. Austria, Finland and Greece (The Science of Reading. Philip Seymour p299)), it is rare to find people who are persistently inaccurate single word decoders i.e. dyslexic in the English-speaking countries' sense of the word. English reading tests commonly assess accuracy of single word decoding but, because of the high word reading accuracy in countries with transparent codes, these tests are not used and reading fluency is assessed instead i.e. the term dyslexia means something completely different in these countries (RRF49 D.McGuinness. p19 & The Science of Reading. Philip Seymour p297) ''If dyslexia [as a distinct and diagnosable decoding disorder] really existed then countries as diverse as Nicaragua and South Korea would not have been able to achieve literacy rates of nearly 100%'' (Stringer).
See D.McGuinness' critique of Goswami's TES article on 'dyslexia' across different languages
www.rrf.org.uk/messageforum/viewtopic.php?t=2995

Myth 16: It is possible to correctly identify and diagnose those with dyslexia living in countries which have transparent writing codes, by testing students' reading fluency, because those with this specific brain defect, despite being accurate single word decoders, find reading effortful and slow.
Facts:
When researchers Landerl, Wimmer and Frith (1997) compared Austrian 'dyslexic' children (slow readers) with English 'dyslexic' children (very inaccurate readers), the Austrian 'dyslexics' were not only far more accurate but also read twice as fast as the English dyslexics.
''Slow reading' is relative; the optimal reading rate varies across writing systems. ''Slowness''..is a function of the writing system, not a property of the child'' (D.McGuinness ERI p191-2)
Reading speed isn't an isolated skill. It's a function of decoding accuracy, text difficulty and general language ability'' (D.McGuinness GRB p14)

Myth 17: Dyslexia can be cured or helped by special balancing exercises, fish-oils, glasses with tinted lenses, vision exercises, listening to modified music, NLP magical spelling, modelling clay words, inner-ear-improving medications, training primitive reflexes, eye occlusion (patching), special fonts, rhyme-analogy games, accupressure....
Facts:
Empirical evidence does not support the use of any of the above remedies - see Room 101
